The basic idea of the framework is to provide a platform for building web-based applications. That means it’s a library nothing like jQuery where you pick and choose what elements of jQuery you want, Cappuccinno is an all-or-nothing solution.
I did find writing the Objective-J code very familiar as I’ve used Objective-C in the past. Is this the new way to write web apps? I don’t know… definitely needs some work to before it truly becomes a v1 product, but it has potential.
Some might cringe that it abstracts the “HTML-ness” away from the web, but I don’t necessarily think that is a bad thing.
It’s definitely a framework you should look into if you are developing a new web-app from scratch. It obviously doesn’t have the widespread use like jQuery does, but that’s not always a bad thing.
